装置。 A vehicle speed sensor detects the vehicle speed, a rotation speed sensor detects the engine rotation speed, and a throttle opening sensor detects the opening of the engine throttle valve. When the automatic transmission changes automatically and the engine speed is above the predetermined fuel cut speed,
a control unit that cuts off the supply of fuel to the engine when the throttle valve is fully closed, and restarts the supply of fuel to the engine when the engine speed drops below a predetermined recovery speed when the fuel is cut off; In the fuel control system for a vehicle with an automatic transmission, the operating range in which the engine speed drops to the recovery speed or less in a short period of time when the throttle valve is fully closed is defined as a fuel cut prohibited zone, and the operating range is outside this fuel cut prohibited zone. A fuel control system for a vehicle with an automatic transmission, characterized in that the control unit performs the fuel cutoff only occasionally.
